Pulling Princes by Tyne O'Connell caught my eye initially in the book, Royal Match. Royal Match is a reconfigured book that includes the first two titles in the Calypso Chronicles: Pulling Princes and Stealing Princes, which you can find on Link+.
If you are a fan of Louise Rennison's character, Georgia Nicholson, you may enjoy the British colloquialisms that run rampant. I enjoy reading books where characters are thrown into totally alien situations. I expected to see many funny situations with the main character, Calypso, who is from Los Angeles. However, Calypso has lived at the British boarding school for a few years, so the "fish out of water" humor never quite materializes. In fact, Calypso actually seems to use British slang, though she claims to have an American accent.
Calypso is an outsider at the posh boarding school, along with her best friend, Star. However, a fake boyfriend leads to opportunities and problems that she never foresaw. A gifted fencer, she soon finds that her hobby leads to the best opportunity of all!
